Prerequisites

1. Get Admin API Key

1. Log in to your Ghost Admin panel (https://your-blog.com/ghost/)
2. Go to Settings → Integrations
3. Click "Add custom integration"
4. Copy the Admin API Key (format: id:secret)

2. Create Configuration File

唯一调用方式：自定义配置文件路径（项目隔离）

Create a JSON config file for your site:

Example: /Users/ethan/.openclaw/workspace/projects/fuye/ghost-admin.config.json

{
  "api_url": "https://fu-ye.com/ghost/api/admin",
  "admin_api_key": "your-id:your-secret"
}

CLI Usage

Method: Custom Config Path (唯一方式)

python3 scripts/ghost.py list --config "../../projects/fuye/ghost-admin.config.json"
python3 scripts/ghost.py create "Title" "Content" --config "../../projects/fuye/ghost-admin.config.json"
python3 scripts/ghost.py upload image.png --config "../../projects/fuye/ghost-admin.config.json"

Common Workflows

Publish with Cover Image

import sys
import os
sys.path.insert(0, os.path.expanduser("~/.openclaw/workspace/skills/ghost/scripts"))
import ghost

# 唯一方式：通过配置文件路径获取配置
config = ghost.get_config(config_path="../../projects/fuye/ghost-admin.config.json")

# Upload cover image
image_url = ghost.upload_image(config, "/path/to/cover.jpg")

# Create post with cover
result = ghost.create_post(

    title="Featured Article",
    content="\x3Cp>Article content...\x3C/p>",
    status="published",
    feature_image=image_url,
    tags=["featured", "tech"]
)

print(f"Published: {result['url']}")
